Topic: lost an entire wheel and drum

Posted By: Road Phantom on 04/11/17 12:15am

I made a turn into a shopping center parking lot, looked back and saw one of my trailer wheels lying in the middle of the road. We have a 2011 Cougar half-ton 5th wheel. The brakes, including backing plates were replaced new last summer. I greased the bearings via the outer zerk fittings this Feb. All this and the bearing failed, breaking the drum. the wheel came off along with the broken drum.
I blame this in part to the size drum they put on these light weight trailers. Mine are ten inches across the inside center. We are careful to load light for trips, despite the 2900 lb carrying capacity which leaves me to believe the Dexter axles are way under par for this trailer which weighs about 7000 empty.

My guess is whoever installed the drums/hubs did not preload the castle nut properly. Most likely too tight. The bearings could have been damaged or failing also. Lots of variables.


Posted By: Superbee Jim on 04/11/17 06:57am

My Dexter axle was ruined and I had to replace the entire axle because of lack of lube to the bearings. I just helped 2 of my friends grease there bearings and if you only pump a few times, it will not lube the outer bearings. After you use the bulk of a tube of grease and fill the entire hub cavity and see it coming out the end by the outer bearing, will you know that both bearings have been greased. Both my friends didn't realize that just a few pumps wont do it until grease comes out by the outer bearing. That is what Dexter recommends.

In my RV experiences I have had issues with bearings on 3 occasions, it's always a bearing issue. Once the drum super heated due to a bad bearing and another time a Dexter never lube axle bearing failed, I caught it due to noise and wheel wobble on turning.

Final piece of advice on those lube zerk fittings, if you over lube them you can blow the grease seal and put grease all over the brake shoes which trashes them. Our last RV came from the factory that way! Better to re-pack the old fashioned way.

Using a grease gun to grease wheel bearing has always been, despite Bearing Buddy and all the other's claims, a poor way to grease wheel bearings. The problem is that as Jim said, the entire cavity must become filled before grease reaches the far bearing. From then on, each time more is pumped in, what greases the far bearing is the old grease that's been drying out in the hub cavity. Far better to go the extra mile, remove the hub, and hand pack both bearings, allowing you to actually inspect the bearings for rust or other damage. Seals are cheap and a new one at the same time assures water and dirt will stay out until the next time you service the axle. Pumping grease in until it oozes out also runs the risk of dislodging the seal. In addition, with the cavity fully packed with grease, as the hub warms up, grease and trapped air will expand pushing more grease out making a mess of the inner sidewall of the tires (and brakes) and causing confusion as to whether the seal is really bad. Properly hand packed bearings and fresh seal will result in clean tires and a timely warning (leaking grease) if something is amiss with the axle. A real problem is that adjusting wheel bearings is becoming a lost art. Most upcoming mechanics are only familiar with sealed bearings now that virtually all autos and most trucks are equipped with sealed bearings on all four wheels. You can read all the books you want but nothing takes the place of an experienced mechanic teaching you by letting you feel the difference between too loose, too tight, and just right bearing adjustment. Sadly many current wrench turners never got that memo.

^^x2^^

For Dexter axles you need to lift the tire off the ground and spin it while hand pumping grease into the zerk. Once grease comes out then you know the job is done. Using a pneumatic grease gun or just pumping grease in without spinning the tire "might" blow the grease seal.

You may have another issue going on for why the wheel came off though other then grease. You may have had a faulty bearing/race or something completely different like loose lug nuts or undersized engineering.


Posted By: GordonThree on 04/11/17 07:43am

I was amazed how easy it was to not only lube by hand, but also remove, clean, repack and replace the bearings. Of course, I only have two wheels. Those with the big trailers and 6+ wheels, I could see it being an all day affair.

I drove the hole-in-the-rock road the other day here in Utah. It has a lot of washboard. We passed a pop-up trailer on the side of the road and the axle was sitting behind it. It had completely fallen off.

I had the same issue in Idaho with my 2012, but I caught it just before the wheel came off. I've since changed my wheel checking to include arriving at a camping spot as I would have noticed the heat the night before instead of seeing the wheel/tire almost in flames at a rest stop 45 miles down the road. The end result was two weeks in Mountain View, Idaho waiting for a new axle.

If the bearings are never properly inspected, how do you know if they are good? They are surely old enough to be bad.


Posted By: Bionic Man on 04/11/17 09:17am

I lost a wheel assembly a few years back. Mine was pulling down the interstate at 65 MPH with my boat in tow behind my 5er.

Anyway, my problem was attributed to either improper torque on my lug nuts, or bad lugs.

If you put a few squirts of grease into the never lube zerks it never gets to the front bearing. You have to fill the cavity in the hub before grease will flow outward.
When you have enough grease pumped in you will see it start to come out around the outer bearing. At that point there's a 50/50 chance you have grease on the brakes.

Well said, goes for boat trailers as well...

At least you were in a parking lot and not the highway. If it had come off at highway speeds it could have injured or killed someone. Like others have said it's best to do it the old fashioned way so you can inspect the bearings.

Being a senior member you have had to see previous posts why it's a good idea to inspect them, and failures of such bearings.


Posted By: Me Again on 04/11/17 11:17am

We had our Cardinal for 11 years and 50 or 60K miles. Every two to three years I removed each wheel and hub to inspect and service the bearings. When we sold it, it still have the original bearings and races.

Blindly just pumping grease in is a big mistake!

I also jack up each wheel and spin and wiggle looking for problems before the long trip between Arizona and Washington. This is going to be easier with the new trailer with 6 point jacks.

I've always hand packed my bearings and have never had a bearing problem. Touch wood. Except of course for Lippert axles which come from the factory with grease leaking all over the brakes.

X2!
Blindly pumping grease in to FILL to cavity is the fastest way to grease the brake shoes!!

Had pack the bearing, place a thick coating of grease on the race and that is all you need.

Poor workmanship.
Should last at least 10 years or 50,000 miles if done properly.

And the sooner you stop using the grease gun the better.

I had a boat trailer wheel and hub come off, destroying the spindle, and had to get a flat bed wrecker.
This was caused by just pumping grease in every year, and not inspecting the bearings.
I would never use a grease fitting to fill my hub, and bearings. I also have a 20 year old ski boat trailer that has oil bath bearings that are original.

You hand packers, how often do you have it done? Do you go by time or miles? This is something I've never done and don't want to experiment with either without someone experienced showing me first.

For all of you that have to inspect the bearings. First do you really know what you're looking at [emoticon]. Second are you sure you're filling every nook and cranny with grease that is not under pressure? And third, do you also do this amount of effort on your car/truck. If so how many miles do you rack up before pulling the bearings on your daily drivers?

Watch a few videos on youtube, it's not that hard, honest. The trickiest part in my opinion is the castle nut.

After about 25,000 miles I took a look at my bearings, and found some heat-stains or whatever they're called on a few rollers, so I went to NAPA and got a new set for both wheels. I've put another 16,000 on since then? Probably will look at them again spring of 2018.

The actual packing is easy but messy. Get a tub of grease, scoop some into the palm of your left hand, and then scoop through the grease with the bearing raceway. Turn and repeat several times, until plenty of grease is jammed into the raceway. Sit that one down and cover with a shop towel, and do the next one. You want to keep dust and debris from blowing and getting stuck in the fresh grease, you'll have to clean it and start over if this happens.

Sealed bearings on my car and truck, Did my car at 120k miles - that took forever, the dealership can do it next time if I still own the car. The truck is under warranty, if it has bearing issues while I still own it, that's Fiat's problem.


Posted By: garyemunson on 04/11/17 05:43pm

On my 4x4 truck, I go 5 years between packings (only put about 5K a year on it). Trailer wheels turn much faster and are probably under much greater load compared to the bigger bearings on the truck so I'll do them every 2 years regardless of miles. Both my truck and the several trailers I had weigh about the same and the front bearings on the truck are much bigger (diameter and width) than trailer bearings. Pack them as good as you can, it'll find it's way to where it is needed. If you've never done one, have someone who has show you what a properly tightened bearing feels like.


Posted By: wilber1 on 04/11/17 05:43pm

Do cars and light trucks even have packable bearings anymore? I do my 5th wheel every two years.

Nothing to be afraid of! Very simple process that just takes a bit of time. It is something you should learn to do if you are going to tow a trailer.

Since about 1980 most cars and light trucks have sealed bearings that do fail on occasion.

But when I had vehicles before the 1970 model year and drum brakes I would pull the drums every two years to check brake linings, clean and repack the bearings with new grease seals.

About the same schedule I do with my trailer.

Posted By: azrving on 04/11/17 06:09pm

I do mine every year because we snowbird and there is no room for a bearing failure or damaged axle. If there is anything noticeable I replace them. $75.00 for four kits and Lucas red sticky grease. A proper inspection isn't just looking at the cups, everything must be cleaned and look at all the rollers and beyond them to the inner race surfaces. The cup is the outer race but there is also an inner surface inside the cage assembly that is often overlooked.

Marketing is great and at the same time why do the ez-lubes have problems 10 to 1 over manually packed bearings?

Proper hand pack should last the life of the shoes.


Posted By: azrving on 04/11/17 06:29pm

My sons ez lube bearings lasted 6 years with regular greasing. The oldman caught it in time when I asked if he had ever removed and inspected

This conversation started because the OP lost a wheel/drum assembly on an easy lube axle. I may be an "old salt" also but sometimes new technology isn't what it is supposed to be. Hand lubing and inspecting still has merit. I have Dexter Never Lube axles and don't feel comfortable not being able to look at the bearings.

Posted By: BiggestRon on 04/11/17 07:59pm

Hey gang,
The OP's situation scared me. After thinking about the conversation, its been 10 years on my bearing. So I have a few questions.

What do you use to clean the old grease from the bearing? Do you use brake clean or some other liquid. I don't have a parts washer. What grease do you recommend.

A lot of the grease can be cleaned out with paper towels. Roll the bearings on the towels to get most of the grease then use brake cleaner. I'm using Lucas red sticky grease

Reminds me of when cars went to electronic ignition. For years if it didn't have points and a condenser, it wasn't reliable. Can't trust that new fancy stuff. LOL.


Posted By: pickjare on 04/11/17 09:22pm

This subject always seems way over-complicated which is the reason the "ez lube" type bearing grease adapters exist now. They are supposed to be the answer to a problem that doesn't exist.

No matter how a bearing is greased, if it isn't adjusted correctly and washer and cotter pin are in place, the thing will fail. That is why the ops tire fell off. I see no picture, but from the explanation it has nothing to do with the drum. Either the spindle overheated and broke or the nut backed off. Doesn't matter how it is greased, just matters that it gets greased. Ez lube axles create a false sense that everything is fine in my opinion.

Op, in the future take your trailer to a qualified technician and pay him/her to service the axles. Then leave them alone for a couple years (well, jack up tire, spin and check for looseness/noise every few trips, but don't grease with ez lube).

Actually I had one of the first year cars that went to electronic ignition. Chrysler came out with it first and I did have trouble with it. They had problems diagnosing the problem because it was intermittent. I'm grateful they corrected the design flaws to give us a modern reliable product.

I like new technology but it doesn't always work as designed.


Posted By: time2roll on 04/11/17 10:41pm

I had a 1970 Mustang with points. Adapted a ~1978 Ford electronic distributor and ignition to the Mustang. Dead on more reliable, more power, lower maintenance.

I have always been about new technology. EZ-lube is not about better technology... only the illusion of lower maintenance.

The real problem with cars as they went electronic ignition was all the vacuum controlled emissions and poorly designed egr that came at the same time.


Posted By: Bmach on 04/11/17 10:53pm

First off "Bearing Buddies" are not for greasing bearings. They put the bearing under pressure with grease to help keep water out of the bearings. As you put a trailer in the water the warm bearing contract leaving a potential void. With the grease under pressure grease is pressed into them not allowing water in. Ez lube axles if done correctly have worked for me. You pump grease in slowly, it goes to the inward beating first, then the outward bearing. Pump slowly and rotate the wheel. I would not try it again on a cold day but that's just me.

Trying to keep this short:
FW-2007 Coachmen 321T-Purchased new in 2007-Full Time Workamping
Jan. 2016-Have new wheels and tires put on 5th wheel.
Feb. 2016-Take FW to have safety inspection performed for registration renewal.
Late Feb 2016-Get Fiver ready for travel to new job in Florida.
Check tires, lugs, lights, etc., Fiver is ready to travel from Texas to Florida. Fiver is in RV Park so I left it hooked up to the power and water. Went to my S&B for few days to pick up DW to travel with me.

Travel day-hook up to TV. Check lights, tire pressure, etc. Off we go. 25 miles later the front street side wheel assembly comes off at 55 mph. Get stopped on highway shoulder. Walk back and recover wheel assembly. Look at hub- two sheared off studs. Limp to exit, find large open area to park. "Hey I can fix this, no problem."
Drive to small town- hit every autoparts place in 20 miles. Finally find enough of the correct size studs. BTW- found lugs nuts loose on Left rear wheel also. Curb side wheels are tight. No movement at all. Just like all four were six days before when checked.
Change studs, install hubs and wheels. Good to go right? Nope, less than 1 mile later I see in mirror wheel angle looks odd. Stop, check lugs, both left side wheels have loose lugs. Huh?
Tighten the **** out of them again-get 1/4 mile and see wobble. I limped to truck stop 5 miles away, stopping every 1/4 mile or less to tighten up. Problem is studs are starting to shear off.

Make it to truck stop. I have two studs left on front left wheel and four on rear left wheel. (Six Lug Hubs)
Call for road side assistance (AAA RV Plus)-No help at all.
Locate Mobile Mechanic-He was able to get to me 8 hrs later- he was out on call.
I had told him on phone that according to my build papers glued in the kitchen cabinet that the RV had "Dexter 5,200 lb axles"
Found out later that night while under the RV that I have Lippert axles. Read directly off the axle.
After all night at truck stop Mobile Mechanic has installed new hubs and bearings.
Off I go to Florida, checking my lug nuts every 25 miles for the first 100 and then at every single stop. All is good.
Fast forward to Nov 2016-Make RV road ready for trip back to Texas from FL. Trip home uneventful from the RV stand point.
While home I fix up a few things on the RV and install two new A/C units. All is good.
Jan 2017-Make ready for road trip to AZ. Do all of the checks, etc. Lugs are good. (BTW-from previous drama I am now fixated on lug nuts)
Off to AZ with DW traveling with me. Five miles from house I see smoke coming off left rear wheel. Whip into Pharmacy parking lot. Dragging brake shoe maybe?
Nope- I see at least one inch of brake pad showing between flange/shield and hub. OK, call Mobile Mech. Mech says I need new axle and it will take 3 weeks to get parts, 2K to tow to their facility, yada, yada, yada..
I pay mechanic for his call out. I jack up axle, remove tire and wheel w/o removing lug nuts. I see spindle/castle nut/three plate washers/inner bearing/grease seal. No outer bearing. Under discolored grease I find what is left of outer bearing. Just a small band of metal.
I locate parts, and for some reason decided to buy a small hub puller. Glad I did. I purchase three complete sets of hubs, bearings, seals, nuts, finger washers, etc.
Glad I did. Go to remove nut-dang it- the threads are partially stripped and the nut is only three threads from the start point. I now know why I have extra plate washers here and no finger washer.(Previous MM jury rigged it? Maybe?)
Cannot get nut to move with fingers. I am glad I keep a 3 ft long crescent on the truck. With lots of grease and care I back off the nut without further damaging threads.
Put new hub/bearings, etc on left side wheels/axles. Do a drive check for 50 miles stopping every 10 or so.
I make my trip to AZ.
I will not use those zerc fittings for greasing my bearings. I will hand pack as I did when I rebuilt it in that parking lot.

My world is ok now.


Posted By: Irelands child on 04/12/17 08:06am

Now on the 3rd page, I've seen some good advice and some that.... well let's leave it at that.

OK, with that said, no one has stated the obvious. Dexter and on their now non-intuitive website, has a bearing handbook. In that information is the recommendation that you pull the drum and inspect and lube the bearings every 12,000 miles or every 12 months, whichever comes first and that includes E-Z Lube bearings. Yes, it is conservative as far as the time frame but the mileage frame is what we 'old timers' used on our automobiles before the days of the front wheel drive cars with sealed capsule bearings. Unfortunately, RV manufacturers don't bother adding this info to their owner's package. Then there is the fact that no-name Chinese made bearings used by Dexter and other bearing users have a poor reputation for longevity as I too found when I pulled the bearings on our Montana after a year and about 5000 miles. Now, 15,000+ miles later, the replacement US made Timken bearings, using a Dexter grease recommendation, show no distress.

If you do continue to use the E-Z Lube system, each empty hub will take about 200 strokes of that grease gun lever along with the best part of a full tube of grease. You also need to lift and rotate each wheel to spread the grease as there is only a single hub entry hole for the grease. You also need to be aware that the seal is the weak point on the system and you can 'blow' by it if you over pressurize that hub by using anything but a hand operated grease gun.

I've posted this elsewhere, but that little hole is the only entry point to grease those bearings while the seal rides the land directly above it (and no, that rough spot is not a defect or failure):

Allways seemed like a huge waste of grease to me, filling a whole hub with grease to do a job that only requires a few onces. I'm still using the same tub of Penzoil 707L that I bought in 2002.

Could be you're right about a huge waste of grease, but I've got a triple axle, plenty of grease, but a only finite amount of time to waste on pulling 6 wheels and repacking same. So I pick wasting some of that grease, and save my time for other things. [emoticon]

I wanted to jump in here and recommend a tool I've used very successfully in the past on travel trailer and boat trailer bearings. the one I have is "OEM" brand UNIVERSAL BEARING PACKER (part #25070), you place the bearing between two plastic cones and screw it together, then pump grease into the center with a grease gun. This forces fresh grease through the bearing and out the sides, pushing all of the old grease etc. out with it. I think this is a lot faster and probably more thorough than doing it by hand.

If you just pack the bearings and leave the large void in the hub greaseless, the grease in the bearing will get hot,melt and run to this void in the hub.

^^^^Well, if you're using EP2 lithium grease, a good wheel bearing grease, and it melts, you've got a very serious problem. EP2 lithium grease melts around 500 degrees F. Even lithium multi-purpose grease melts around 350 degrees F. So if you're melting grease, having the void full of grease isn't going to help much.

Won't centrifucal force sling the grease around the hub tubes outer area??

I learn to hand packet bearing as a young kid working in service stations back when they had service! Early 60's! Never have had a bearing failure to date. Chris

I call FUD.
I just pulled mine at 10 years and maybe 35,000 miles... grease was still just fine on the cheepo bearings and all looked good.

X2!
I have packed many a wheel bearing in my life, and never pulled one later to find the grease the "Melted" and ran to the center.
I have been packing bearings for over 50 years.

Where do you come up with this stuff, marketing is great these days.

Possibly melt was a poor choice of wording. And not everyone goes out and buys xyz premium spaceshuttle lithium grease.

Sure is funny that grease liquifies and drips from grease guns on an normal summer day.

And were not all talking to and about people who routinely maintain their hubs. Most who will read this could care less about their hubs and bearings.

The oil that you see leaking out of an unused grease gun is oil that has separated, or come out of suspension, not melted. The turning bearing will actually keep that from happening since it keeps the oil in suspension by the rotation of the bearing. Just like oil and water, let it sit and the oil will rise, keep it agitated and it will disperse, somewhat, in the water.

If you let the bearing sit long enough, some of the oil will indeed run to the lowest point. Another good reason to use your trailer rather than let it sit. [emoticon]

Well I for one don't buy cheap grease the cost difference for a tub is insignificant, not to buy the best at least the better grade.[emoticon]

I use wheel bearing grease. Not sure if it is internet approved. It doesn't melt.

"Four hungry bearings and rings that won't seal. Oh, it's a fine time to leave me loose wheel."

All I can say is we might be beating a dead horse here, some will do what they want.
But the bottom line is that in over forty plus years of doing all my own maintenance on vehicles and now of course trailers, if the trailer like mine now has EZ-lube I pump grease in till it comes out with the new stuff showing, BUT!
That does not mean you should not check bearings visually and you should be looking at the brakes over time, and for that I imagine all drum brakes require undoing the axle nut and taking drum off, so that is the time to also check bearings, but yes you can use the greasable ones, but every so often and especially before long trips do yourself a favour and check bearings and repack manually.
Can't hurt.
